Group control elevators control the operation of cars effectively and efficiently, decide which car will serve a hall call, and notify the waiting passengers of the car (hereinafter referred to as a service car) (for example, by turning on a warning light). (hereinafter referred to as the "forecast") in an effort to improve service to passengers waiting at the boarding station. This service car forecast allows waiting customers to know in advance which car will serve them, so it has a psychological effect (for example, alleviating frustration while waiting and giving them a sense of security). There is something very big.

However, when traffic becomes congested, the forecasted cars become full and pass the hall call, which often causes the forecast to be changed to another car (hereinafter referred to as forecast change). be. Such changes in the forecast will disappoint the expectations of passengers waiting on the platform, increasing their sense of impatience, and if changes in the forecast are issued frequently, they may become distrustful of the forecast. Moreover, when a car is full, the allocation operation is performed again at that point, which adds additional waiting time until the newly allocated car responds, creating another problem of long-waiting calls. . In other words, in cases where the forecast is simply incorrect, such as when another car arrives before the forecasted car, the waiting time will be shorter, although there is a problem of customers distrusting the forecast, but the waiting time will be shorter, but the waiting time will be shorter. Changing the forecast due to passage causes the problem of increased waiting time in addition to the problem of customers distrusting the forecast.

One of the group management methods is called the assignment method. In this method, when a hall call is registered, the service situation (for example, waiting time) for passengers waiting at the hall is predicted, an evaluation value for assignment is calculated, and a service car is assigned to the hall call based on the evaluation value. Then, the car operates by sequentially responding to car calls and landing calls assigned as described above. Conventionally, in such an allocation method,
In order to reduce the above-mentioned problems related to forecasts, evaluation values regarding allocation are calculated based on not only the waiting time but also the prediction of full traffic. For example, the evaluation value when a hall call is assigned to car No.
Ij Here, tk: Predicted waiting time for hall call k P k : Probability (%) that the service car for hall call k will pass full (expected value regarding full passage) A: Weighting coefficient (constant value) N: Registered The car is calculated using a formula called the number of hall calls, and the hall call is assigned to the car with the minimum evaluation value Ij. With such an allocation method, waiting time and forecast changes can be evaluated in a well-balanced manner, and waiting time and forecast changes can be reduced. However, in the conventional allocation method, the value of the weighting coefficient A in the above equation is changed at most depending on traffic patterns such as when going to work in the morning, during lunch break, when leaving work in the evening, and during normal times that occupy most of the day. Since the value of the weighting coefficient is set appropriately in advance,
It is not known whether the value is really appropriate for the traffic condition until actual traffic measurements are taken. Furthermore, since traffic demand varies even within the same traffic pattern, it is difficult to maintain sufficient forecast accuracy using weighting coefficient values set for each traffic pattern. Therefore, in some cases, the accuracy of the forecast may become extremely low, leading to increased distrust of the forecast and the frequent occurrence of long-waiting calls.

Now, car a is assigned to the 5th floor up call, and 4
When the vehicle is stopped in the ascending direction and the door is open, the assignment signal 14a is "H", but the full traffic signal 15a is "L", so the output signal 20r of the AND gate 20 is also "L". , full passage detection signal 23m
is "L". When car a is full on the 4th floor and departs from the 4th floor to answer a car call on the 6th floor, the full traveling signal 15a becomes "H", and when car a reaches the 5th floor, the car position signal 16a becomes "H". H”. If car a does not have a car call on the 5th floor, car call signal 17a is "L",
Since the output signal of the NOT gate 26 becomes "H", the AND gate 20 changes the full passage detection signal 20r for car a from "L" to "H", and therefore the full passage detection signal 23m also changes from "L" to "H". H”. Then, either the car a passes through the 5th floor and the car position signal 16a becomes "L", or the assignment of the car a to the 5th floor upward direction is canceled by the full passage detection signal 20r of the car a, and the assignment signal 14a When becomes "L", the full passage detection signals 20r, 23m change from the "H" state to the "L" state again. In this way, when a full passage is detected for the fifth floor upward landing, the pulse counter 24 increments its content by one and outputs a full passage number signal U5m.
If car a has a car call on the 5th floor,
The car call signal 17a is "H" and NOT gate 2
Since the output signal of car 6 becomes "L", the full passage detection signal 20r of car a remains at "L" and no full passage is detected. On the other hand, when the 5th floor up call is registered and the hall call registration signal 29 changes from "L" to "H", the pulse counter 25
increases the content by one, and the hall call number signal U5
Output n. In this way, the full passage detection circuit U5 detects a full passage for the boarding hall in the upward direction on the 5th floor, but the full passage detection circuits U1 to U4 and D6 to D2 detect the full passage for other boarding halls in the same way. is detected, and the number of full passage times and the number of hall calls in all the halls are added by adders 9 and 10, respectively, and the respective sums are calculated.

Full traffic total number signal 9 calculated as above
a, and the hall call total number signal 10a are each 5.
times, 20 times, divider 11 calculates 5÷20=0.25
is output. On the other hand, since the value of the hall call total number signal 10a (=20 pieces)>the value of the constant value signal 8 (=10 pieces), the output signal of the comparator 12 becomes "H",
An "H" signal is input to the T point of the storage device 13, and the output signal (=0.25) of the divider 11 is stored in the storage device 20. Therefore, the full passage rate of 4m is set to 0.25.

次に、満員通過率信号4mの値により重み係数

Next, the weighting coefficient signal 5m is modified based on the value of the full passage rate signal 4m. In FIG. 4, if the weighting coefficient level signal 35m is now 3, since 0.25>the value of the set value signal 31 (=0.2), the output signal of the comparator 33 is "H" and the 5 minute When the periodic signal 18 is "H", the output signal of the AND gate 38 becomes "H" and the content of the pulse counter 35 increases by one. Therefore, the weighting factor level signal 35m becomes 4 from 3, and the weighting factor signal 5m is set to 4×20=80 by the multiplier 37.
Furthermore, if the weighting coefficient level signal 35m is 3 and the full passage rate signal 4m is 0.05, then the comparator 3
Since the output signal of 4 becomes "H", when the 5-minute cycle signal 18 is "H", the output signal of the AND gate 39 becomes "H" and the content of the pulse counter 35 decreases by one. Therefore, the weighting factor level signal 3
5m becomes 2 from 3, and the weighting coefficient signal 5m is set to 2×20=40 by the multiplier 37.

In this way, the full passing rate of the assigned cars is calculated under the current traffic conditions, and when the full passing rate is so bad that it exceeds the upper limit,
The weighting coefficient A in the formula is set to a large value to perform allocation with emphasis placed on reducing the number of crowded passages. In addition, when the above-mentioned full passage rate is lower than the lower limit value, the weighting coefficient A in the formula is set to a small value, and the allocation is made with more emphasis on shortening waiting time than reducing the number of crowded passages, thereby improving forecast accuracy. It is possible to reduce waiting time while keeping it at a certain level.

In the above embodiment, the full passage rate was calculated based on the number of occurrences of full passage with respect to the number of hall calls registered in a certain period. The method is not limited to this, and the full passage rate may be calculated by the number of full passages for a certain number of hall calls each time the number of registered hall calls reaches a certain number, or only the number of full passages may be detected. It is clear that it is possible. It is also clear that when the weighting coefficient A in the formula is set for each hall call, the accuracy can be further improved by calculating the full pass rate for each hall direction and modifying the weighting coefficient for each hall direction. In short, it suffices to use something that represents the frequency of occurrence of packed passages.

In addition, in the above embodiment, a case was described in which the weighting coefficient for the probability of a full passage is expressed in a method of allocating hall calls using an evaluation formula such as the following, but this is limited to the case where the prediction of a full passage is expressed as a probability. isn't it. For example, it may be the number of hall calls that are likely to be filled with passengers.

As explained above, in this invention, packed passages within a predetermined period of time are detected, and the weighting values related to packed passages are automatically corrected depending on the increase/decrease in the frequency of occurrence of packed passages, so traffic conditions may vary. sufficient forecast accuracy can be maintained.
As a result, it is possible to suppress the occurrence of changes in the forecast due to crowded passages, and also to suppress the occurrence of long waiting calls.
